Manned space flight is the most complex, difficult and demanding system engineering in human space activities. After five years, China's manned space mission was reopened. The astronauts will fly to the newly decorated "outer space residence" this time. This manned space mission is a key part of the overall construction task of China Space Station. According to the plan, China will carry out the 1 1 mission this year and next, including three space station module launches, four cargo spacecraft launches and four manned spacecraft launches. In 2022, China will complete the on-orbit construction of the space station and become a national space laboratory.
The starry sky is boundless and there is no end to exploration. Only by continuous innovation can the Chinese nation move towards the future better. Shenzhou-12 manned mission is the fourth mission in the key technology verification stage of this round of space station, and it is also the first manned mission in the space station stage. The staff summed up the important position of the task in eight words: it is very important to connect the preceding with the following. According to the plan, after the Shenzhou-12 spacecraft is in orbit, it will be docked with the front port of Tianhe core cabin by autonomous rapid rendezvous and docking, and form an assembly with Tianhe core cabin and Tianzhou-2 cargo spacecraft; Three astronauts will be stationed in the core cabin, work and live for three months according to the synchronous work and rest system of heaven and earth, and then return to the Dongfeng landing site in the spacecraft return cabin. From Shenzhou 5 to Shenzhou XI, in just over ten years, China has become the third country in the world to independently master manned space shuttle technology, space extravehicular technology and rendezvous and docking technology. Now, China Space Station has officially entered the stage of on-orbit assembly and construction, and the "three-step" strategy is coming to an end.
Exploring the vast universe, developing the space industry and building a space power are our unremitting pursuit of the space dream. Since September 2 1 and 1 1 were established, shenzhou spaceship, Tiangong-1 target aircraft, Tiangong-2 space laboratory, Tianzhou-1 cargo spacecraft, Tianhe core module of space station, Tianzhou-2 cargo spacecraft ... China's manned spaceflight industry has been self-reliant, overcome difficulties and finally entered the space station. From one person for one day to many people for many days, from in-cabin experiments to spacewalks, from short-term stays to medium-term stays ... Key technologies such as round-trip between heaven and earth, space exit, rendezvous and docking have been mastered one after another, and China's manned space program has been solidly promoted step by step. The space industry has continuously set new records, the space launch capability has been significantly improved, and space science and technology have advanced by leaps and bounds. The pace of marching from a space power to a space power is forceful, and the exciting launch has condensed the sweat and wisdom of China astronauts, showing China's determination and courage to achieve scientific and technological independence.
Looking up at the bright starry sky and working hard on the ground, a more brilliant future for China Aerospace has begun. Looking back, a history of space development is a history of self-improvement of developing countries. The vast number of astronauts have bravely climbed the peak and kept moving forward on the journey of space development, making contributions to building a space power and a world science and technology power, and constantly making new contributions to realizing the goal of "two hundred years" and realizing the Chinese dream of the great rejuvenation of the Chinese nation. Take the older generation of astronauts as an example, vigorously carry forward the spirit of "two bombs and one satellite" and manned space flight, strive for self-improvement, innovate and surpass, dare to overcome all difficulties and obstacles, and bravely climb the peak of space science and technology, so that the people of China can explore space more steadily and further, and realize the great dream of building a space power at an early date.
